It's an older P160, use on 2 1/2" dredges, now they called them PHP160


Thank you sir!
Curiouisly its physicaly larger than the original motor/pump (Dahlke DP-125. (No idea of GPM)) that came on my Dahlke 4b micro dredge. Same inlet & outlet sizes, but bigger body. The later Dahlkes came with a Dahlke DP-150 so I assume the 125 was undersize. The Dahlke is a someday dredge I bought with no hose or jet for a someday project so I have never run it.
 

To see what the approximant GPM of your pump try getting a 55 gallon barrel and fill it with water and set up your pump/eng.. to pump it out using a stop watch to see how long it takes = GPM :coffee2:
 

With a 1¼" outlet it's probably an old P100. I think it puts out around 125gpm. Could be a P90. The P200 stated above has a 1½" npt outlet...
